Raju The Leader (3/31/2010)SQL Server 2008 introduces a new feature called Resource Governor which enables Database Administrators to manage SQL Server workload and critical system resource consumption. Resource Governor enables DBA to specify limits on the amount of CPU and memory which the incoming sessions to the SQL Server can use. In a production environment DBA's will come across scenarios when there could be sudden spike in CPU and memory utilization thereby resulting in slow responses to query requests. These issues happen when there is unpredicted workload execution like long running TSQL queries, database backups being performed etc. The solution to these issues is the use of Resource Governor which enables DBA's to differentiate workloads and allocate shared resources as they are requested, based on limits you specify for resources like CPU and memory. The resource governor limits can easily be reconfigured in real time with minimal impact on the workloads that are executing.

Revenant (3/30/2010)Well, the question is incorrect, anyway - RG is also available in the Evaluation Edition. So that "only" without this version mentioned is IMO misleading.

Maybe, but the answer really is obvious (how can anyone get it wrong even by making an intelligent guess? After all, SQL2k8 is carefully packaged so that all major new features are in developer edition to get the developers hooked and in enterprise edition to ensure that those hooked developers genrate the maximum revenue for MS).What I really don't like about this question is the appalling carelessness: a question with no verb, and an explanation that says that SQL 2k8 is supplied only in developer and enterprise editions are serious defects compared to the trivial mistake of thinking that evaluation edition doesn't exist (evaluation is of course, like developer edition, intended to get us hooked on things that will make us buy enterprise edition; or am I just being cynical here?).
